Patented Dec. 31, 1929 UNITED STATES PATENT OFFICE ARTHUR IJL LEVY, OFBROOKLYN, NEW YORK, ASSIGNOR 'IO SUPERLOID MANUFACTUR- ING COMPANY,INC., OF BROOKLYN, NEW YORK, A CORPORATTON OF NEW YORK OE'H'II-IALMICMOUNTING Application filed April 9,

This invention relates generally to ophthal mic mountings, particularlymountings wherein lens rings or frames, as well as the nose piecestherefor, are formed of non-metallic material; this application being acontinuation in part of my application Serial No. 280,604, filed May 25,1928.

As is generally known, at the present time non-metallic mountings of thetype wherein the lens rings and bridge are formed in one piece requirethe dealer to carry in stock a large variety of sizes of such mountingsin order to properly fit different types of faces. It frequently occurs,even where the dealer is possessed of a large variety of sizes of suchmountings, that it is necessary to affix an extra piece on the bridge toespecially adapt a mounting for flat noses. Again, difficulty isfrequently experienced in adapting thegrips to the nose of the wearer sothat proper positioning of the lens rings with respect to the eyes maybe had without discomfort to the wearer. It is an object of the presentinventionto provide an ophthalmic mounting of the type underconsideration which is constructed in such manner as to overcome theobjection common to similar types of mountings heretofore used.

The objects of the invention are carried out in the details ofconstruction hereinafter set forth in the description and particularlyspecified in the claims, reference being had to the accompanyingdrawing, wherein Fig. 1 is a rearelevation of an'ophthalmic mounting ofthe type under consideration constructed in accordance with theinvention,

Fig. 2 is a sectional view taken substantial ly upon line 22 of Fig. 1,the scale of drawing being slightly enlarged,

Fig. 3 is a detail view in section taken upon line 33 of Fig. 2,

Fig. l is a detail perspective view of one of the connectors employed incarrying out the invention,

Figs. 5, 6, 7, 8 and 9 are combined fragmentary elevations andperspective views illustrating various modifications of the connectorfor the lens frame an'dnose grip and illustrating their manner ofapplication.

Referring now to the drawing, and particu- 1929. Serial No. 353,773.

larly to Figs. 1 to 3 inclusive, the lens rings or frames are indicatedat 5, while the bridge connecting them is indicated at 6; the saidringsand bridge being continuous or of one piece and made of shell,horn, zylonite or other non-metallic material or-composition. In thepresent instance, the frames have associated therewith the hingedtemples represented at 7, but it will be understood that the inventionis equally applicable to mountings of the Oxford type.

The nose pads or grips for the mounting are indicated at 8, and areformed of nonmetallic material substantially similar to that of whichthe rings and bridge are constructed. The advantages of nose griipsformed of such material are well recogniZed in the art, and it is to themanner in whichsuch pads are connected to the rings or frames that thepresent invention is directed.

The nose grips o1 pads 8 each have associated therewith a metallicconnector 9 to afford connection between the nose grip andthe ring withwhich it is associated. The connectors 9 are formed of pliable orductile metal, capable of being flexed to a great variety of positionsor angles by the use of proper instruments, yet possessing sufiicientrigidity and resiliency to firmly hold the mounting upon the nose of awearer. The metal is also of such nature as to create the desiredretaining pressure in forcing the pads into contact with the nosewithout becoming permanently deformed.

Each connector is provided at one end with laterally and oppositelydirected wings 10 to provide a relatlvely great area in that particularend of the connector. The said end, together with its wings, is embeddedin the nose grip or pad 8 in the formation of the latter, so that whenthe grip has become set or hardened, the connector will be securely andfirmly anchored therein. The opposite end of the connector is providedwith similar wings or projections 11, each ofwhich carries a prong 12disposed at right angles to the plane of the projection 11. These prongsare preferably disposed in parallelism. The connector for the greaterpart of its length is preferably of uniform width, and is bent uponitself intermediate its ends in substantially U-shape as shown. In theproper application of the connectors to the lens frames, the prongs 12are embedded in the frames so as to securely anchor the same to theframe. \Vhen properly positioned, the body portion of the connectorswill be disposed outwardly or in the general direction of the lensescarried by the frames.

In the modification disclosed by Fig. 5 of the drawing, the connector isrepresented generally at 9 and includes a flat pliable metal body ofsubstantially rectangular formation with divergent prongs 13 at its endsto be embedded in the non-metallic nose pad 8 and lens frame 5respectively.

In Fig. 6, the connector 9 has its ends pronged as shown, and theseprongs have inwardly directed hooks or detents 14: to act as anchoragesfor the ends of the connector embedded in the nose pad and lens frame.

In Fig. 7 the connector 9. has its ends 15 deflected as shown so as toengage within the material of which the nose pad and lens frame isformed and to secure the ends firmly therein.

In Fig. 8 the same general type of connector 9 is shown, the ends beingpronged and the extremities of the prongs having enlargements whichconstitute lateral deflections 16 to perform the function of anchorages.

In Fig. 9 the connector 9 has laterally deflected wings 16 at its ends,which wings have openings 17 through which retaining elements 18 may bepassed to secure the ends 16 firmly with the material of which the nosepad and lens frame is formed.

\Vhen constructed in this manner, the connectors afford a great latitudeof adjustment in positioning the nose grips. The adjustment of the bodyportion of each connector may be made with the use of opticians pliersor other grips, and due to the ductility of the metal of which theseconnectors are formed, lateral and longitudinal adjustments to even themost minute degree may be easily and quickly made. The optician is thusenabled to adapt a given mounting to the face of practically anycustomer. Lateral, longitudinal and angular adjustments of the nose padsmay be easily made, and the mounting may be properly adjusted to theface notwithstanding irregularities or deformities in the nose of thewearer.

The several views of the drawing disclose a number of ways in which thepliable connector may be constructed to perform its purpose, and whilethe foregoing is a description of the invention in its preferredembodiments, it is nevertheless understood that strict limitationthereto is not implied as further variations in the detailed structureand assemblage may be made without departing from the scope of theinvention as defined by the claims.

Having thus described my invention, I claim:

1. In an ophthalmic mounting, lens rings formed of non-metallicmaterial, nose grips formed of non-metallic material, a connector formedof pliable metal uniting each nose grip with its respective lcns ring,and the ends of said connectors engaged in said lens rings and gripsrespectively.

2. In an ophthalmic mounting, lens rings and nose grips formed ofnon-metallic material, a connector formed of pliable material for eachnose grip and lens ring, wings projecting from one end of each connectorand embedded in the body of said nose grips, and the opposite ends ofsaid connectors secured to said rings.

3. An ophthalmic mounting comprising a pair of lens rings and a bridgemember formed in one piece and of non-metallic material, nose gripsformed of non-metallic material, arms of pliable metal, each arm havinglaterally directed wings at one end embedded in the material of the nosegrips, laterally directed projections at the opposite end of each arm,prongs extending at substantially right angles to said projections andparallel with each other, said prongs being embedded in said rings, andthe intermediate portions of said arms being of substantially uniformbreadth and bent into substantially U-shape.

4. In an ophthalmic mounting, lens rings, nose grips formed ofnon-metallic material, a connector formed of pliable material for eachnose grip and lens ring, wings projecting from one end of each connectorand embedded in the body of said nose grips, and the opposite ends ofsaid connectors secured to said rings.

In testimony whereof, I hereby aflix my signature.

ARTHUR M. LEVY.
